When internal encryption is enabled for a HCP for cloud scale system, the Key Management System service provides key encryption keys for storage components. If the service restarts, the vault is sealed and stored objects can't be decrypted. If the vault becomes sealed, you must provide a quorum of unseal keys (three of the five provided when encryption was first enabled) to reopen the vault and resume encryption and decryption.
Important: Don't try to initialize the vault manually outside of HCP for cloud scale. Doing so results in data loss.
The vault is unsealed.
